1.  Purpose

The purpose of these procedures is to establish a system to manage the risks to health and safety associated with work in confined spaces, in accordance with legislative requirements and the University’s Work Health and Safety Policy.

2.  Definitions

Competent person A person who has acquired through training, qualification and/ or experience the knowledge and skills to carry out the required task in relation to confined or other restricted spaces.
Confined space

An enclosed or partially enclosed space that

  • is not designed or intended primarily to be occupied by a person; and
  • is, or is designed or intended to be, at normal atmospheric pressure while any person is in the space; and
  • is or is likely to be a risk to health and safety from:
    • an atmosphere that does not have a safe oxygen level; or
    • contaminants, including airborne gases, vapours and dusts, that may cause injury from fire or explosion; or
    • harmful concentrations of any airborne contaminants; or
    • engulfment- 

but does not include a mine shaft or the workings of a mine.

Examples of confined spaces at the University include, but are not limited to:

  • pipes and sewers
  • storm water manholes
  • chemical storage tanks
  • pressure vessels
  • boilers
  • lift pits
  • flues
Confined space entry permit  A document which gives permission for entry into a confined space for the work to be undertaken. 
Safe Work Method Statement (SWMS)  A written document that sets out the confined space work activities to be carried out, the hazards and risks arising from those activities and the measures to be put in place to control the risks. 
Standby person 

A person who is assigned to

  • continually monitor the wellbeing of those inside the confined space, and if practicable, observe the work being carried out; and
  • initiate appropriate emergency procedures when necessary.
Workers University staff, contractors and sub-contractors and their employees, labour hire company employees, trainees, students gaining work experience and volunteers. 
Workplace  A place where work, study or research is carried out for the University and includes any place where a worker goes, or is likely to be, while working, studying or undertaking research. 

3.  Scope

These procedures apply to all workers at workplaces owned, managed or controlled by Flinders University and any place where work is performed by a worker on behalf of the University. 

These procedures do not apply to work in confined spaces during field trips. Staff planning to undertake work in confined spaces during field trips must refer to the University’s Field Trip Guidelines for the requirements for such work.

6.  Confined Spaces Register

6.1  The Buildings & Property Division must

  • identify all confined spaces at University workplaces; and
  • maintain a Confined Spaces Register, including the following:
    • description and location of each space;
    • hazards associated with individual spaces; and
    • risk assessments for the hazards identified.

6.2  The Confined Spaces Register must be updated as required with any addition, removal or change, and in any case, must be reviewed annually.

7.  Signs and barricades

7.1  The entry points to each confined space must be permanently signposted and secured to prevent unauthorised entry.

7.2  Before any work in relation to a confined space starts, signs must be erected to prevent entry of persons not involved in the work.

7.3  Signs must warn against entry by people other than those listed on the Confined Spaces Entry Permit and must be placed at each entrance to the confined space.

7.4  Signs must be in place while the confined space is accessible, including when preparing to work in the space, during work in the space and when packing up on completion of the work.

8.  Confined Spaces Risk Management

8.1  Identification of hazards

Buildings & Property must identify reasonably foreseeable hazards for each confined space that could cause harm to people. Such hazards may be

  • Restricted entry or exit
  • Harmful airborne contaminants
  • Unsafe oxygen levels
  • Fire and explosion
  • Engulfment
  • Uncontrolled introduction of substances
  • Biological hazards
  • Mechanical hazards
  • Noise
  • Manual tasks
  • Radiation
  • Environmental hazards
  • Electrical hazards
  • Physiological and psychological demands
  • Hazards outside the confined space
  • Skin contact with hazardous substances

8.2  Risk assessment

8.2.1  The risk associated with each identified hazard must be assessed by a competent person in accordance with the University WHS Risk Management Policy and must be recorded in writing as part of the job specific Safe Work Method Statement (SWMS).

8.2.2  The risk assessment must take into account the nature of the confined space, the work that needs to be done, the range of methods by which the work could be done, emergency response procedures and the competence of the persons to undertake the work.

8.2.3  A generic risk assessment may be carried out where the confined spaces, their hazards and the work to be performed are the same. A non-generic risk assessment must be carried out on an individual confined space if there is any likelihood that a worker may be exposed to greater, additional or different risks.

8.2.4  Risk assessments and Safe Work Method Statements must be reviewed and revised whenever there is a change in the work environment.

8.2.5  A copy of the SWMS must be kept for 28 days, or if a notifiable incident occurs in connection with the work to which the SWMS relates, for 2 years after the incident occurs.

8.3  Risk Controls

8.3.1  Any risk associated with working in a confined space should be eliminated if it is reasonably practicable to do so. Where possible, an attempt should be made to eliminate the need to enter the confined space altogether.

8.3.2  If it is not reasonably practicable to eliminate the risk, the risk should be minimised so far as is reasonably practicable by using the hierarchy of controls as outlined in the University WHS Risk Management Policy.

8.3.3  If entering a confined space cannot be avoided, then a safe system for working inside the space must be developed, documented as part of a job-specific SWMS and implemented. The following matters must be considered:

  • the nature of the space
  • the concentration of oxygen or airborne contaminants
  • the work and work method
  • emergency procedures

9.  Confined Space Entry Permit

9.1  No-one is permitted to enter or work in a confined space unless authorised to do so by a Confined Spaces Entry Permit issued by the University’s Buildings & Property Division.

9.2  The Confined Space Entry Permit form must be completed by the person who is to undertake work in the confined space and must include documented evidence of competencies for the work to be undertaken, the completed risk assessment of the confined space and a job-specific SWMS.

9.3  A Confined Space Entry Permit is also required when a person enters a confined space to conduct an initial hazard identification or risk assessment.

9.4  The Confined Space Entry Permit must

  • specify the confined space to which the permit relates;
  • record the names of persons permitted to enter the confined space and the period of time that the work will be carried out;
  • set out the risk control measures based on the SWMS; and
  • contain space for acknowledgement that work in the confined space has been completed and persons have left the space.

9.5  The Confined Space Entry Permit must be authorised by a competent person in the University’s Buildings & Property Division who is nominated and authorised to issue such permits on behalf of the University.

9.6  Each Permit only applies to one confined space and allows one or more workers to enter that space.

9.7  Permits must be kept until the work is completed, or if a notifiable incident occurs, for at least 2 years after the confined space work to which the permit relates is completed.

10.  Isolation

10.1   All potentially hazardous services, as determined by the hazard identification and risk assessment process, must be isolated before any person enters a confined space to prevent

  • the introduction of services though piping, ducts, vents, drains, conveyors, service pipes and fire protection equipment;
  • the activation or energising of machinery in the confined space;
  • the activation of plant or services outside the confined space that could adversely affect the space;
  • the release of any stored or potential energy in plant; and/or
  • the inadvertent use of electrical equipment.

10.2   The method of isolation should be determined on a case by case basis taking into account the hazards and types of services in the space.

10.3   Isolation procedures as set out in the Plant Safety Policy must be followed.

11.  Atmosphere

11.1  A safe atmosphere must be ensured, so far as is reasonably practicable, during work in a confined space. A safe atmosphere in a confined space is one that:

  • has a safe oxygen level
  • is free of airborne contaminants or any airborne contaminants are in concentrations below their allowable exposure standard (if any)
  • any flammable gas or vapour in the atmosphere is below 5% of its Lower Explosive Limit (LEL).

11.2   Atmospheric testing and monitoring must be conducted by a competent person to determine appropriate control measures. Re-testing and continuous monitoring may be necessary if the risk assessment indicates that conditions may change due to the work being conducted.

11.3  Where a flammable atmosphere may exist in the confined space and there is a risk of fire and explosion, all ignition sources in the vicinity must be eliminated.

11.4   If it is not reasonably practicable to ensure that the confined space contains a safe level of oxygen or airborne contaminants, then appropriate respiratory protective equipment must be provided.

11.5  Summary of conditions

Criteria Entry Entry under special conditions No Entry
Oxygen 21% Below 21% with air supplied respiratory protection More than 21%
Atmospheric contaminants Below exposure standards Above exposure standards with suitable personal protective equipment Above exposure standards
Temperatures No extreme temperatures   Extreme temperatures
Flammable contaminant LEL below 5% LEL between 5% - 10% with continuous monitoring flammable gas detector Equal to or greater than 10% LEL

12.  Communication and safety monitoring - Standby Person

12.1  Before a worker enters a confined space, a standby person must be assigned to monitor continuously the wellbeing of those inside the space, if practical to observe the work being carried out and to initiate appropriate emergency procedures when necessary.

12.2  There must be continuous communication with the worker from outside the confined space.

12.3  The standby person must maintain a log of persons entering and leaving the confined space.

13.  Entry and exit procedures

For the entire period the confined space entry permit is valid, procedures must be in place to indicate when any worker is in the space.

14.  Signs and barricades

14.1  Before work in relation to a confined space starts, signs must be erected at each entrance to the confined space to prevent entry of persons not involved in the work.

14.2  When a confined space is not in use, appropriate signage and barriers should be erected and security devices (eg locks) installed to prevent unauthorised access.

15.  Information, Instruction and training

15.1  Workers and their supervisors must have the skills and knowledge to understand the hazards associated with working in the confined space, the contents of any confined space entry permit and the control measures implemented for their protection.

15.2  All workers with work activities related to confined spaces must be trained and assessed as competent to perform those activities. The training must cover

  • the nature of all hazards associated with a confined space;
  • the need for, and appropriate use of, risk control measures;
  • the selection, use, fit, testing and storage of any personal protective equipment;
  • the required contents of any relevant confined space entry permit; and
  • emergency procedures.

15.3  Re-training and refresher training must be provided at a frequency depending on how often workers are required to carry out tasks associated with entry to or work in confined spaces.

15.4  Records of all training provided to workers in relation to confined space work must be kept for 2 years.

16.  Emergency procedures

16.1  First aid and rescue procedures to be followed in an emergency must be established and practiced with relevant workers to ensure they are efficient and effective.

16.2  Openings for entry and exit must be of sufficient size to allow emergency access,  openings must not be obstructed and any plant, equipment and personal protective equipment provided for first aid or emergency rescue must be maintained, tested and in good working order.

16.3  First aid and rescue procedures must be included on the Confined Space Entry Permit.

16.4  Workers performing rescue must be adequately trained and competent to perform rescue procedures.

16.5  If possible, the rescue should be performed from outside the confined space.

16.6  Rescuers must be provided with and must wear appropriate respiratory protective equipment if they are entering a confined space in an emergency.
